1. Percussion cap.
  2. Not even in the ball park amigo. It is not military, not explosive, and very commercial. I will have to think about what sort of hint I can give that just won't flat out give it away. Can't have the wheels coming off this early!:yelwink2:
  3. Ferrule at the end of a pencil.
  4. Nope, it isn't part of a pencil or a pen. It is however an integral part of a bigger part that serves a very important purpose.
  5. Penile implant for Shane? :D
  6. just a bit large for that.
  7. Some kind of spacer.
  8. Not a spacer
  9. What's it made of? Hollow? Solid?
  10. It is solid, and I'm going to guess that it is possibly steel. If not that some other form of metal that is able to stand up to high temp.
